OIL-BURNING s'rovn Application filed .Tune' 7, 1929.- Serial No. 369,083.

My invention relates to oil burning stoves of the type disclosed in my co-pending application, Serial No. 278,855, filed May 18 1928, which has now matured intoPatent No.

v 1,743,402, Jan. 14, 1930, and has for its object to simplify. and improve upon said stove.

More particularly it is my object to pro- 1 vide in a stove of the type having a pair of upright fines and a winding combustion chamber connecting sald flues at their lower ends,'a more substantial bracing structure connecting the flues so thatthe stove as a whole is more rigidand solid in construction than previously. 1

A further object is to eliminate a number of parts previously considered necessary in supporting a fuel tank in such a manner as v to discharge fuel from said tank into one of the tines without entirelycutting off the flow of air through said flue.

Another object is to provide a stove capa bleof supporting a tank of larger capacity than heretofore.

.Another object is to provide a stove that may be used either as a tank heater or-as a brooder stove having certain ing it to both uses. 1

Another object is to provide a stove. that is self-extinguishing in the event of an ex- The foregoing objects are all solved in a structure embodying a combined brace and fuel tank structure connected to fines. Such an arrangement makes it possible to employ portions of the fines as'end walls for the tank;

. thus cutting clown the-amount of material necessary, makes it possible to make a direct I connection between the tank and the inside of one of the fiues below the top of the fines 49 for a drip valve, and gives a much stronger bracing construction would afford. a

features adapt I With.these and other objects in view, my

' inventionv consists in the construction, ar-

rangement and combination of the VaI1011 S parts of my device, whereby the objects co'ntemplated are attained,- as hereinafter more fully set forth, pointed out in my claims,

ings, in which:

than a simple braceand illustrated in the accompanying draw- Fig. 1 is a plan view of the stove.

'Fig. 6 is a side elevation of the stove used 80 as a brooden v I have used the reference character 10 to indicate generally the Winding combustion chamber of the stove whichis identical to that described in my co-pending application. The two fiues are indicated at 11 and 12, respectively, and the supporting legs 13 and 14 are similar in construction to that of my said patent.

The tank comprising" the side walls 14, joined to the sides of the flues 11 and 12 and the top. and bottom Walls 15 and '16,-respectively, cut out to fit the curve of the flues 11 and 12 and joined thereto to form a completely enclosed tank. The method of joining the tank to the fines is by Welding due to the V apair offuel delivery pipes 17 and 18, re-

spectively, each having a threaded end upon Which may be threaded the drip valve 19 When the drip valve is attached to one of the fuel delivery pipes, the other one is plugged or capped as at 18 in the drawing. The valve 19v is'provided with a sediment pocket 20, fuel delivery passage 21 and a threaded valve element 22 to close the passage 21. 99 The tank'is provided with a filling neck 23, which is closed by a threaded cap 24. A hood 25 is mounted on an arm 26,- Which is provided at its end with an opening to receive the neck 23, whereby the arm is pi 'otally mounted. r

The hood 25 may be swung to cover either of the flues.

v The drip .valve 18and thus either of the flues may be used as an intake flue while the other flue serves as a discharge chimney.

The intake flue is normally covered by the hood 25, the exhaust chimney being unobstructed so as to allow it to be connected to a chimney pipe or the like.

It is thought to be evident from the foregoing description how the objects hereinbefore set forth are accomplished.

The simplicity of construction, strength and cheapness are obtained through the integral tank and brace construction shown;

The adaptability of the stove as a brooder stove or a tank heater is derived from the adjustable leg structure, which is fully disclosed in my said patent. The stove may be successfully r employed as a brooder stove by raising the stove proper relative to the legs so as to provide a space below the stove, as

bottom ofthe tankas possible.

\ The stove is well fitted for use as a tank heater, due to the imperforate construction of the flues 11 and 12 and the combustion chamber 10. In this regard, I may state that an essential element of the invention involved in the present stove and in the stove disclosed in my saidpatent is the construction whereby the stove is formed as a tube chamber starting with oneof the flues 11 or 12, including the combustion chamber 10 and ending with the other flue. This tube is imperforate from the lower extremity of the combustion chamber to a level substantially above the upper extremity of the combustion cham= ber so that should fuel be fed to the stove faster than it can beburned, the excess fuel will ultimately fill the combustion chamber in such a manner as to cut off all passage of air through the stove. When this occurs, it will be impossible for further burning to occur and the fire will be smothered by the fumes produced in the vertical flues 11 and 12.

It is impossible for oil to overflow from the stove until long after thefire has been extinguished. Thus the fire hazard which is a very important problem in connection with all oil burners, particularly of the type employed for brooders, is well coped with in my burner.

Another very important advantage of the integral tank construction resides in the fact that the oil supply'tank is kep constantly warm by conduction from the stove. This keeps the fuel in a high fluid state, preventing it from becoming thick and insuring that it will flow freely to the dripvalve.

In Fig. 6, I have shown the stove embodied in a brooder. It will be noted that the legs have been' extended so that the stove is raised considerably from the floor, which is indicated by the line 30; A hover 31 is provided, which is supported uponthe two flues of the stove.

The exhaust fine is connected to the roof of the building, in which the hover is in stalled by means of a chimney 32 and the in 33 to a downwardly projecting pipe 3i, which terminates very close to the floor 30 was to suck cold air from the floor. tion' causes a down draft which pulls the heated -air from the hover down to the floor and disposes of the cold air at the floor.

Some changes may be made in the construction and arrangement of the parts of my invention without departing from the real spirit and purpose of my invention, and it is my intention to cover by my claims, any modified forms of structure or use of mechanical equivalents, which may bereasonably included within their scope.
